"We're excited to announce that Skype users can now video call their Skype contacts on Lync, and vice versa!" said company officials in a blog post announcing the new capability.

In May 2013, Microsoft officials said they would deliver Skype-Lync federation in two steps. In 2013, Skype and Lync users were able to integrate contacts, presence, instant messaging and audio calling across the two services. At that time, officials said video connectivity between the two would happen until mid-2014.

Earlier this year, Microsoft execs pushed back the due date for Skype-Lync video integration until year-end 2014.When Microsoft announced last month that the company would be changing the name of Lync to "Skype for Business," officials also said that they planned to update Microsoft's Skype clients with H.264 codec support so as to be able to provide video integration between Skype and Lync 2013.
